二台子金矿床产于古生代中泥盆世的碳酸盐地层中,矿床受构造控制,金的粒度很细,呈浸染状分布于岩石中,黄铁矿以及砷矿物(砷黝铜矿、含砷黄铁矿)是主要载金矿物.矿床的基本地质特征与美国内华达州的卡林金矿相似.本文以地质特征为基础,从数学地质角度对该矿床进行讨论,找出与Au关系密切的元素和蚀变,模拟成矿过程,为找矿提供又一地质信息标志.
The Ertaizi gold deposit was produced in the Mesozoic carbonate basin in the Middle Devonian. The deposit is controlled by tectonics. The gold is finely grained and disseminated in rocks. Pyrite and arsenic minerals (arsenic, Arsenopyrite) is the main gold-bearing mineral.The basic geological characteristics of the deposit are similar to that of Carlin Gold Mine in Nevada, USA In this paper, based on the geological characteristics, this deposit is discussed from the point of mathematical geology to find the close relationship with Au Element and alteration to simulate the mineralization process and provide another geological information sign for prospecting.
